ALFRED L. COBB, 0F LONG BEACH, CALIFORNIA.

TRUSS PAD.

Application filed November 12, 1923.

To all @07mm it may concer/n Be it known that l, ALFRED L. COBB, acitizen of the United States, residing at Long Beach, in the county ofLos Angeles and State of California, have invented a new and usefulTruss Pad, of which the following is a specification.

The present invention has truss construction, and more the pad thereof.

rlhe primary object of the invention is to provide means for securing apad to its supporting rod in a manner to permit of unrestrictedadjustment of the pad so that the user may adjust the pad for a betterapplication of the pad.

Another important object of the invention is to provide a pad which maybe secured in its position of adjustment, eliminating any possibility ofthe pad getting out of adjustment under ordinary conditions.

`With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the cornbination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure l is a rear elevational view disclosing a pad constructed inaccordance with the invention as secured to its supporting rod.

Figure 2 is a side elevational view thereof.

Figure 3 is a sectional view taken on line 3 3 of Figure l.

Figure 4 is a sectional view taken on line a-t of Figure l.

Referring to the drawing in detail, the reference character 5 designatesa supporting rod to which the usual cloth material forming the straps ofthe truss, is secured.

The pad includes preferably a solid body portion indicated at curved inthe usual and well known manner so that the same will properly fit thebody of the user.

Secured to the flat or rear surface of the pad body, is a plateindicated at 7 which has curved ends conforming to the curvareference toparticularly Serial No. 674,350.

ture of the pad structure, the central por tion of the plate beingcurved and offset at 8, to accommodate the rod 5, it being understoodthat the curvature of the offset portion 8 conforms to the curvature ofthe rod 5 to closely grip the rod 5.

rlhe body portion 6 is also formed with a groovel indicated at 9, whichgroove is disposed under the offset portions 8 of the plate 7 toaccommodate the rod 5, permit ting the rod to move with respect to thepad, or vice versa, but at the same time restrict movement of the padlongitudinally of the rod -5.

A cut out portion l() is formed in thc pad and accommodates the sleeve1l fitted over the rod 5, the ends of the sleeve being designed toengage the end walls of the cut out portion 10 to further restrictlongitudinal movement of the pad with respect to its supporting rod.Extending through a threaded opening formed in the sleeve l is a setscrew 12, adapted to engage the supporting` rod associated therewith tosecure the sleeve in vvarious positions of adjustmentto insure againstthe pad slipping` longitudinally of its supporting rod.

The plate 7 is formed with a central cut out portion 14 providing aclearance for the sleeve, the width of the cut out portion 'lli beinggreater than the Width of the tubular member to allow of movement of thepad, in a rotary plane with respect to the rod. As shown, the screw l2is of a length to contact with the plate 7, when the plate moves toadjust itself, thereby restricting movement of the body portion withrespect to the rod 5.

Screws 13 secure the plate 7 to the bodyr portion of the pad and insurethe plate be` ing properly held against accidental displacement. Fromthe foregoing it will be obvious that due to the construction as shownand described, the pad or body portion 6 is free to adjust itself tovarious movements of the body of the user, but at the saine time berestricted from movement longitudinally of the supporting rod.

l claim:-

A truss pad including a body port-ion, said body portion having a grooveextending transversely thereof throughout the width of the body portion,a plate having a central offset. portion overlying the groove, Saidlongitudinal and rotational movement of the plate having a. central outout portion, a. pad with respect to the supporting rod. Supporting rodadjustably mounted in In Jtestimony that I Claim the OIegOiIlg 10 thegroove, a collar mounted on the rod and 21S my OWH, have hGPG'fO LXG/dmy Signa- 5 disposed in the out out portion7 and adjust UW@- able meansfor securing the collar in position7 and said collar adapted to limitthe ALFRED L. COBB.
